There are some misconceptions going around on the list about laser ignition. Just having the laser beam going through the mixture will not ignite it. The laser beam needs to be focused by a lens, then the higher intensity at the focal point causes a breakdown in the gas, creating a small ball of plasma that ignites the mixture.

The LASER would be mounted in a safe cool place and fire through a light wire.
 
Or a multi facet reflective target in each rotor face to direct beams in every direction, or high pressure injection right through a laser beam.
 
Or the same idea but into a prechamber like the huge Curtis Wright rotaries, so it can run on any flammable liquid, like Jet A or waste oil,
or raw crude oil, or LNG? The mind boggles.................
